Re: Connect 2 computers (10 miles away) using wireless tech.
Oh, it's not impossible.
The issue is line-of-sight.
If you can get two satellite dish antennas, 18 inch or so, and one of them is on the top of a tall building... it could work.
I don't have the link anymore, but there was somebody that wrote an article on this. He wanted DSL and it was across the valley from his place.
The provider refused to run cable to him.
So, he made a deal with somebody on the other side of the valley.
A pair of sat dishes, pointed at each other.
Cat 5 cable, antenna lead adapters, wireless access points like Apple Airport Base Stations.
The do-it-yourself model is called a "Can-Tenna".
Basically, you get a used Sat dish, take off the mounted receiver and bolt on a large soup can with both ends cut out and soup removed, of course.
For the actual antenna it's just a sewing needle measured and cut to the right length.
You mount this to the soup can, attach the dish to your wall and run the coax cable inside your house.
The interesting thing is that with parabolic dishes you don't need amplifiers. The normal signal strength is enough for quite a ways if focused parabolically.
And as for hacking, the signal spreads out slowly. At a distance of 10 miles the cone of the signal will be, mhhm, a hundred yards wide?
Probably not that much.
But at the source, it's only 18 inches wide.
So a hacker would have to be either right on top of your antenna or hanging in the air at the 5 mile point to catch the signal.
Of course the question of permission to use the bandwidth does come up...
